フィルタを配しそ成る音声再生回路。In a video disc player that plays back a video disc record made by superimposing one frame of video information and FM audio information per revolution on a spiral recording track, there are three modes: normal playback mode, forward fast playback mode, and forward slow playback mode. An audio reproduction circuit that includes a forward reproduction mode detection circuit that detects the reproduction mode setting and allows the derivation of audio information, and a dynamic low-pass filter that momentarily suppresses the passband of the audio information in synchronization with the interlaced pulse. .
